IMPLEMENT FOR APPLYING GLAZIERS" POINTS.

Specification of Letters latent. Patented Sept. 18, 1917- Application filed. April 14, 1917. Serial No. 162,105.

To all whom it may concern:

Be it known that I, JOHN A. MOFFAT, a subject of the King of Great Britain, residing at Hamilton, in the Province of On tario and Dominion of Canada, have in vented certain new and useful Improvements in Implements for Applying Glaziers Points, of which the following is a specification.

.This invention relates to improvements in implements for inserting glaziers points in sash members to hold the glass in position prior to the application of the putty or other cement, and has for one of its objects to improve the construction and increase the ciliciency and utility of implements of this character.

Another object of the invention is to pro-.-

vide an implement of this character including a detachable abutment or driving member,'whereby the driving member may be renewed when worn, without discarding the remainder of the implement.

Another object of the invention is to provide an implement of this character having a driving or abutment member detachably and reversibly arranged in the stock of the implement, so that the abutment member may be reversed in position when one driving edge becomesworn or impaired.

\Vith these and other objects in view, the invention consists in certain novel features of construct-ion, as hereinafter shown and described and then specifically pointed out in the claims; and in the drawings illustrative of the preferred embodiment of the invention Figure 1 is a view of a portion of a window sash and a portion of the glass supported upon the rabbet of the same with the implement shown inoperative osition.

Fig. 2 is a section on the line 2-2 of Fig. 1.

Fig. 3 is an enlarged perspective view of a portion of the improved implement illustrating its construction.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

The glass is usually supported in position within the rabbet of the sash by triangular shaped members called glaziers points and constructed of sheet metal, usually zinc, and are forced into the sash and in contact with the glass prior to the application of the putty. Heretofore these points have been driven into the sash by blows imparted thereto by the side edge of a chisel or like implement, but this operation is tedious and the glass is liable to be-scratched or broken by careless handling of the implement. The implement which is disclosed in. this application is designed to force the points into the sash vwithout danger of breaking or marring the glass and, at the same time causingthe points to bear with requisite pressureagainst the glass to hold the latter in place. For the purpose of illustration a port-ion of a sash is represented as a whole at 10, and provided with the usual rabbet 11 for supporting the glass, a portion of the latter being represented at 12. One of the points is indicated at 13 after it has been forced into the body of the sash, and another of the points. is represented in. position to'be forcedinto the sash.

' The improved implement 7 comprises a stock or body of coacting portions 14-15, the portion 11 being directed obliquely to the longitudinal aXis of the stock. The portion 15 has an operating handle 16 attached thereto, as shown. The portion 14: of the stock is formed with a flat face 17 and with a transverse recess indicated at 18 spaced from its free end. The portion of the stock in advance of the recess 18 isreduced in thickness and the reduced portion curved away from the recess, as shown at 19. The end of the reduced portion of the stock is rounded or concaved, as represented at 20.

Fitting within the recesslS is a block device 21, preferably of hardened steel, the outer face ofthe'block being flush with the face 17 of the stock. The block is detachably supported withinthe recess 18 by a clamp screw 22 or other suitable fasteninl device. lVhen thus arranged the edge of the block 21 is located next to the curved face 19 of the reduced portion of the stock, the curved face 19 and the block 21 coacting to produce a recess with the outer face of the block forming the inner wall of the recess.

With an implement thus constructed when the flat face 17 and the outer face of the block 21 are disposed upon the glass 12, the handle 16 will stand obliquely to the longitudinal plane of the glass and thus provide space for the fingers of the operator, so that the fiat faces may bear upon the glass in oprati g th implement. After th g ss 12,

has been. located in position upon the rabbets 11 of the sash, a number of the members 13 are thrown indiscriminately upon the glass and the implement employed to separate one of the points from the others and push it over the glass with one of the terminals in position where the point is to be inserted. The implement is then disposed in position over the point with the forward edge of the block 21 against the adjacent edge of the point, as illustrated in Fig. 1. Pressure is then applied to the handle 16 to force the point into the sash until the rounded end 20, bears against the sash. If the material of the sash is abnormally hard the implement is moved from side to side with a rolling motion to vibrate the member 13 laterally to assist in forcing it into the sash. The roundcd end 20 materially aids in the operation by enabling the implement to be given the requisite rolling or vibratory motion. The face 17 and the outer face of the member 21 lying flatly upon the glass cause the shoulder or abutment portion of the member 21 to effectually coact with the point 13 in forcing the latter into the sash, While at the same time the rounded terminal being disposed in advance of the forward edge of the member 21 limits the inward movement of the point and leaves the latter projecting to the requisite extent, generally about an eighth of an inch.

The block 18 is preferably square, or corresponding in width to the width of the portion 1% of the stock, while the recess 18 is of corresponding size. Then by forming the block 21 with all four edges fiat, when one edge is worn the block can be reversed in position to bring another of the edges in operative position. Thus the life of the implement is materially increased without increasing the expense or weight. When the member 21 is worn out or impaired it can be renewed at a trifling expense without the 7 necessity of discarding the remainder of the implement.

The improved d vice is simple in construction, can be inexpensively manufactured and sold at a. small expense, and will be found very convenient for glaziers in applying points to the sash.

1. An implement of the class described comprising a stock having a handle at one end and a transverse seat spaced from the other end, the body of the stock being re duced in advance of the seat with the lower face of the reduced portion curving upwardly and outwardly away from the seat, and a block secured within the seat with its outer face flush with the adjacent face of the stock and its forward edge forming a glaziers point engaging abutment, the curving of the lower face of the reduced portion operating to prevent the separation of the abutment from the glaziers point in event of the stock being elevated at its handle end.

2. An implement of the class described comprising a stock having a handle atone end and a transverse abutment spaced from the other end, the body of the stock in advance of the abutment being reduced with the lower face of the reduced portion curving upwardly and outwardly away from the abutment, the curving of the lower face of the reduced portion operating to prevent the separation of the abutment from the glaziers point in event of the stock being elevated at its handle end.

An implement of the class described comprising a stock having a handle at one end and a transverse abutment spaced from the other end, the body of the stock in advance of the abutment being reduced with the forward face of the reduced portion rounded and the lower face curving upwardly and outwardly away from the abutment, the curving of the lower face of the reduced portion operating to prevent the separation of the abutment from the glaziers point in event of the stock being elevated at its handle end.

In testimony whereof I aflix my signature.
